Third Party Services

This plugin connects to the CO2Track API to retrieve CO₂ emission data for display on your website.

  • Service: CO2Track (https://co2track.nl)
  • API endpoint: https://raoaqlcbhkuuaerjxqmu.supabase.co/functions/v1/widget-data
  • Data sent: Widget Key (a public identifier, e.g. ct_xxxxxxxxxxxxxxxx)
  • Data received: Company name, CO₂ value, year, confidence level, previous measurement, scope label
  • When: Each time a page containing the widget is loaded by a visitor (cached for 5 minutes)
  • Terms of Service: https://co2track.nl/voorwaarden
  • Privacy Policy: https://co2track.nl/privacy

No personal visitor data is collected, stored, or transmitted to CO2Track. The widget only sends the Widget Key to identify which emission data to display.

  1. Install the plugin via the WordPress plugin directory, or upload the co2track folder to /wp-content/plugins/
  2. Activate the plugin through the ‘Plugins’ menu
  3. Go to Settings CO2Track and enter your Widget Key
  4. Add the CO2Track Widget block to any page or post, or use the [co2track] shortcode
Do I need a CO2Track account?

A free account at co2track.nl is recommended for live data mode. You can also use the plugin in static mode by entering CO₂ values directly.

Is the plugin free?

Yes, the plugin is completely free. CO2Track offers free and paid plans — the widget works with all plans. The CO2Track watermark is always shown on free and starter plans.

What data is sent to CO2Track?

Only the Widget Key is sent to the CO2Track API to retrieve your emission data. No visitor data, IP addresses, or personal information is collected or transmitted.

Does it work with page builders?

Yes. The shortcode [co2track] works with Elementor, Divi, WPBakery, Beaver Builder, and any other page builder that supports shortcodes. The Gutenberg block works in the native WordPress editor.

Can I have multiple widgets on one page?

Yes. Each widget instance works independently. Use multiple shortcodes or blocks with different settings.
